 * @test
 *
 * @summary converted from VM Testbase nsk/jdi/ThreadReference/stop/stop001.
 * VM Testbase keywords: [quick, jpda, jdi, quarantine]
 * VM Testbase comments: 7034630
 * VM Testbase readme:
 * DESCRIPTION:
 *     The test for the implementation of an object of the type
 *     ThreadReference.
 *     The test checks up that a result of the method
 *     com.sun.jdi.ThreadReference.stop()
 *     complies with its spec:
 *     public void stop(ObjectReference throwable)
 *           throws InvalidTypeException
 *     Stops this thread with an asynchronous exception.
 *     A debugger thread in the target VM will stop this thread with the
 *     given Throwable object.
 *     Parameters: throwable - the asynchronous exception to throw.
 *     Throws: InvalidTypeException -
 *             if throwable is not an instance of java.lang.Throwable in
 *             the target VM.
 *             ObjectCollectedException -
 *             if this object or the asynchronous exception has been garbage collected.
 *     See Also: java.lang.Thread#stop(Throwable)
 *     when a ThreadReference object has not been garbage collected,
 *     hence ObjectCollectedException is not expected to be thrown.
 *     The test works as follows:
 *     The debugger program - nsk.jdi.ThreadReference.stop.stop001;
 *     the debuggee program - nsk.jdi.ThreadReference.stop.stop001a.
 *     Using nsk.jdi.share classes,
 *     the debugger gets the debuggee running on another JavaVM,
 *     creates the object debuggee.VM,
 *     establishes a pipe with the debuggee program, and then
 *     send to the programm commands, to which the debuggee replies
 *     via the pipe. Upon getting reply,
 *     the debugger calls corresponding debuggee.VM methods to get
 *     needed data and compares the data got to the data expected.
 *     In case of error the test produces the return value 97 and
 *     a corresponding error message(s).
 *     Otherwise, the test is passed and produces
 *     the return value 95 and no message.
 * COMMENTS:
 *     The test ws modified to fixe the bug:
 *     4637894 TEST_BUG: stop001a does not check object against null
